The ES Act establishes a legislative framework for preventing persons from being killed or injured by electricity, and preventing property from being destroyed or damaged by electricity. The ES Act places the primary electrical safety duty on a person conducting a business or undertaking, who must ensure the business or undertaking is conducted in a way that is electrically safe. Duties are also placed on officers of a person conducting a business or undertaking, workers and other persons at a workplace, as well as electricity entities, designers, manufacturers, importers, suppliers, installers, repairers and persons in control of electrical equipment. The Work Health and Safety Act 2011 (WHS Act) requires persons who have a duty to ensure health and safety to ‘manage risks’ by eliminating health and safety risks so far as is reasonably practicable, and if it is not reasonably practicable to do so, to minimise those risks so far as is reasonably practicable. The WHS Act provides a framework to protect the health, safety and welfare of all workers at work. It also protects the health and safety of all other people who might be affected by the work. The WHS Act places the primary health and safety duty on a person conducting a business or undertaking, who must ensure, so far as is reasonably practicable, the health and safety of workers at the workplace. Duties are also placed on officers of a person conducting a business or undertaking, workers and other persons at a workplace. In terms of electrical safety, where the ES Act and the WHS Act both apply, the ES Act takes precedence. Foreword This Code of Practice on how to manage electrical risks in workplaces is made under section 44 of the ES Act. A code of practice is a practical guide to achieving the standards of electrical safety required under the ES Act and the Electrical Safety Regulation 2013 (the ES Regulation). A code of practice applies to anyone who has an electrical safety duty in the circumstances described in the code. In most cases,

However, due to differences in national health, social security and occupational safety and health systems, the content, capacity, coverage and provisions of OHS vary considerably across national contexts. Obtaining a better understanding in terms of such similarities and varia- tions internationally is essential as such comparative information can help inform evidenced-based decision-making on OHS at both policy and practice levels.

    Mesothelioma in Australia 2018 Published August 2019 4 in 10 people diagnosed Each year in Australia, between 700 and 800 people are diagnosed are aged 70–79. with mesothelioma. In 2018, 699 people died from this rare and aggressive cancer, based on Australian Mesothelioma Registry (AMR) data at 1 May 2019. Australia has one of the highest measured incidence rates of mesothelioma in the world (Bray et al. 2017). According to analysis of the AMR, the ‘average’ Australian with mesothelioma: • was male Since 1986, the 5-year relative survival rate • was diagnosed at around 75 years of age has remained stable • was exposed to asbestos in both occupational and at around 5.5%. non-occupational settings • lived for around 11 months after diagnosis. This report presents the latest available information from the AMR, supplemented by data from the National Mortality Database (NMD), the Australian Cancer Database (ACD) and the National Death Index (NDI). In 2018, 699 people died What is mesothelioma? from mesothelioma— Mesothelioma is a form of cancer in the mesothelium—the a rate of 2.8 per 100,000 protective lining on the inside of body cavities and the outside of population. internal organs. In 2018, around 94% of cases reported to the AMR (where tumour location information was available) were pleural mesothelioma, which occurs around the lungs, and 6% of cases were mesothelioma in other areas of the body. More information on the diagnostic characteristics of cases of mesothelioma diagnosed in 2018 is available in Mesothelioma in Australia 2018: Data tables. Despite most commonly occurring in the chest, mesothelioma is not a lung cancer and receives different forms of treatment (Cancer Council 2019a).

  • National Dust Disease Taskforce Interim Advice to Minister for Health
    National Dust Disease Taskforce Interim Advice to Minister for Health DECEMBER 2019 National Dust 2 Disease Taskforce Foreword The Hon. Greg Hunt, MP Australian Minister for Health Dear Minister, As Chair of the National Dust Disease Taskforce (the Taskforce), I am pleased to present this interim advice to you. Since the establishment of the Taskforce on 26 July 2019, members of the Taskforce have worked to understand the issues underlying the re-emergence of silicosis, in particular the emerging trend of accelerated silicosis among workers in the engineered (composite) stone industry. We anticipate that lessons learnt through our review have the potential to inform Australia’s approach to handling other occupational dust diseases. Through an intensive consultation period, we have listened to stakeholders and taken a systems view approach, to identify the core issues that sit along the supply chain for engineered stone. We have also identified where there are immediate opportunities to develop a nationally consistent approach to ensuring safe workplaces, health screening of exposed workers and potential research into the pathogenesis, monitoring and treatment of the accelerated silicosis disease. On behalf of the Taskforce, I would like to acknowledge and thank all those who have contributed to our discovery phase. They include representatives from government, industry, clinical, legal, research, consumers, unions, families and most importantly, from those workers at risk of, or affected by, accelerated silicosis. I present to you our

    ELECTRICAL SAFETY PROCEDURE SCOPE This Procedure relates to all activities under the management and control of Monash University in Australia and applies to affected workers, students, contractors and visitors. PROCEDURE STATEMENT This procedure details the requirements for ensuring electrical safety for all electrical equipment and installations used: • On campuses (including residences) and sites under the management and control of Monash University; • As part of University-sanctioned activities by workers and students of Monash University, contractors, visitors, hire companies or any other person or associated agency. 1. Abbreviations BPD Buildings and Property Division COES Certificate Of Electrical Safety EPOD Electrical Portable Outlet Device ESV Energy Safe Victoria MUOHSC Monash Occupational Health & Safety Committee OHS Occupational Health and Safety OH&S Monash Occupational Health and Safety S.A.R.A.H Safety and Risk Analysis Hub RCD Residual Current Device 2. Risk Management Electrical hazards present a significant risk to Monash University workers, students, stakeholders and contractors. Though some areas (workshops, laboratories, etc.) and work tasks (research, maintenance and construction activities, etc.) may have a higher risk factor, all electrical hazards require evaluation and risk mitigation to prevent harm. OHS risk management must be completed in accordance with the OHS Risk Management Procedure: • Before activities involving electrical equipment can commence; • Before procuring new electrical equipment; • Before the introduction of new procedures or processes that use electrical equipment; and • When procedures or processes that use electrical equipment are modified. Specific electrical hazards and risk controls are not documented in this procedure due to the manner in which they can arise and the scope and complexity of work tasks completed throughout Monash University.
